#Python 3+ Script for jsonifying feedback table data as of 2017-11-12 made by Jordie0608
#Apologies for the boilerplated and squirrely code in parts, this has been my first foray into python
#
#Before starting ensure you have installed the mysqlclient package https://github.com/PyMySQL/mysqlclient-python
#It can be downloaded from command line with pip:
#pip install mysqlclient
#
#tgstation no longer supports MySQL which has been superseded by MariaDB, a drop-in replacement.
#Before running this script you will need to migrate to MariaDB.
#Migrating is very easy to do, for details on how see: https://mariadb.com/kb/en/library/upgrading-from-mysql-to-mariadb/
#
#You will also have to create a new feedback table for inserting converted data to per the schema:
#CREATE TABLE `feedback_new` (
#  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
#  `datetime` datetime NOT NULL,
#  `round_id` int(11) unsigned NOT NULL,
#  `key_name` varchar(32) NOT NULL,
#  `key_type` enum('text', 'amount', 'tally', 'nested tally', 'associative') NOT NULL,
#  `version` tinyint(3) unsigned NOT NULL,
#  `json` json NOT NULL,
#  PRIMARY KEY (`id`)
#) ENGINE=MyISAM
#This is to prevent the destruction of legacy data and allow rollbacks to be performed in the event of an error during conversion
#Once conversion is complete remember to rename the old and new feedback tables; it's up to you if you want to keep the old table
#
#To view the parameters for this script, execute it with the argument --help
#All the positional arguments are required, remember to include prefixes in your table names if you use them
#An example of the command used to execute this script from powershell:
#python feedback_conversion_2017-11-12.py "localhost" "root" "password" "feedback" "SS13_feedback" "SS13_feedback_new"
#I found that this script would complete conversion of 10000 rows approximately every 2-3 seconds
#Depending on the size of your feedback table and the computer used it may take several minutes for the script to finish
#
#The script has been tested to complete with tgstation's feedback table as of 2017-10-23 01:34:06
#Due to the complexity of data that has potentially changed formats multiple times and suffered errors when recording I cannot guarantee it'll always execute successfully
#In the event of an error the new feedback table is automatically truncated
#The source table is never modified so you don't have to worry about losing any data due to errors
#Note that some feedback keys are renamed or coalesced into one, additionnaly some have been entirely removed
#
#While this script can be run with your game server(s) active, it may interfere with other database operations and any feedback created after the script has started won't be converted
